如何从int正确设置UIColor? [英] How to I properly set UIColor from int?
问题描述
我正在尝试通过为其分配值来设置UITextView
的textColor
.
I am trying to set the textColor
of a UITextView
by assigning it a value.
我在程序中的较早版本
textView.textColor = 0x000000;
但是后来,当我有
textView.textColor = 0x888888;
弹出一个致命错误,说:"ARC不允许将'int'隐式转换为'UIColor *'.
a fatal error pops up saying: "Implicit conversion of 'int' to 'UIColor *' is disallowed with ARC".
如何将我的int转换为UIColor以正确设置文本颜色?为什么它不能与0x000000一起使用,而不能与0x888888一起使用?
How do I convert my int to a UIColor to properly set the text color? Why did it work with 0x000000 and not 0x888888?
推荐答案
正如您提交的答案一样,这不是答案.UIColorFromRGB
是上面在@implementation
处定义的宏,例如
as par you submited answer this is not an answer UIColorFromRGB
is a Macro that define above at @implementation
like
#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0];
然后您可以像
textView.textColor = UIColorFromRGB(0x888888);
您可以使用其UIColor
属性在目标c中设置文本bg-color等的颜色
you can use its property of UIColor
for setting color of text bg-color etc in objective c
